While the Bifen L/P Insecticide Granules is a great product for armyworms, you will not get a lot of coverage from it. However, the liquid version Bifen IT would be a great alternative for armyworm control and would also cover more area.
For low or general maintenance applications, Bifen IT is applied at 0.18 - 0.25 fluid oz in 1 gallon of water per 1000 sq. ft (8 fl oz to 11 fl oz in 44 gallons of water per acre).
For severe/higher populations or when grass is taller than 1 inch, apply Bifen IT at 1 fl oz in 1-2 gallons of water per 1000 sq ft (44 fl oz in 44 to 88 gallons of water per acre).
Please view the product label for more information.
Bifen L/P Insecticide Granules are applied using a lawn spreader to dry turf then immediately watered in with atleast 0.5 to 1 inch of rainfall or irrigation. Once the granules have disolved into the soil, it is safe for childen, pets and wildlife that may enter the treated area. This product could be a hazard to birds if the dry granule is swallowed but once they are watered any risk would not be an issue.
Since your specific spreader is not included on the label for Bifen L/P Insecticide Granules, you will need to calibrate your spreader. You can view our helpful instructional video on How to Calibrate a Lawn Spreader by clicking here.

Bifen L/P Insecticide Granules would just applied to soil areas around the tree and lawn as directed on the label for target pests.
Both the liquid and granules would be fine to use in areas where kids and pets may enter after the applications have completely dried, typically after 4-6 hours. For perimeter barrier applications we typically suggest using a liquid because it is more versatile. You can spray on the ground, a band around the bottom of the house, around doors and windows and other areas where pests may try to enter the structure and then apply Bifen L/P Insecticide Granules further out in the lawn.
